Название: Learning the bash ShellАвторы: Newham C., Rosenblatt B. Аннотация: O'Reilly's bestselling book on Linux's bash shell is at it again. Now that Linux is an established player both as a server and on the desktop Learning the bash Shell has been updated and refreshed to account for all the latest changes.
